Subject [jira] [Commented] (SOLR-8873) Enforce dataDir/instanceDir/ulogDir to be paths that contain only a controlled subset of characters
Date Mon, 04 Apr 2016 20:32:25 GMT

    [ https://issues.apache.org/jira/browse/SOLR-8873?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15224995#comment-15224995

Jan Høydahl commented on SOLR-8873:
-----------------------------------

Is this motivated from real life problems? What bugs do you expect as long as people use legal
file names from Javas point of view? In Norway we have the special characters {{æøå}} and
other countries have other characters they may want to use in a folder name. Why disallow
if there is no problem?

> We currently support any valid path for dataDir/instanceDir/ulogDir. I think we should
prevent special characters and restrict to a subset that is commonly used and tested.
> My initial proposals it to allow the Java pattern: {code:java}"^[a-zA-Z0-9\\.\\ \\\\\\-_/\"':]+$"{code}
but I'm open to suggestions. I'm not sure if there can be issues with HDFS paths (this pattern
does pass the tests we currently have), or some other use case I'm not considering.
> I also think our tests should use all those characters randomly.
